RIKEN SPring-8 Center Safety Design Group
Group Director: Shunji Goto (D.Eng.)
The group evaluates radiation safety and radiation shield performance by analyzing the measured data. The group also carries out R&D on beam loss monitors with high functionality and R&D on the performance improvement of the radiation monitors.
- Research of radiation physics and behaviors for XFEL accelerators
- Research of radiation shielding and protection for XFEL accelerators
- Radiation safety design for advanced XFEL facility
- Research and developments for radiation monitors including electron beam loss and beam halo monitors of advanced XFEL accelerators.
